Taking a classic pistol into the future, the BrickArms Longslide Automatic
Pistol adds greater accuracy (not to mention style!) to the M1911 design with the dual
additions of a longer barrel and a top-mounted laser sight.
Just put the red dot where you want the blast to go!

(Disclaimer: All BrickArms tiny toy weapons are made of solid ABS plastic, designed to be used with LEGO® toys.
They cannot shoot bullets and cannot be made to fire bullets in any way. Again, they are a TOY! T-O-Y Toyee!)
